AVR Memory Usage
Device: atmega1284
Program: 101324 bytes (77.3% Full)
(.text + .data + .bootloader)
Data: 6890 bytes (42.1% Full)
(.data
Also when you print out the size in the make file, how much SRAM does it
indicate your program is using?

So I would recommend that you put in the ASSERT for the LDL_PEDANTIC()
macro.
Secondly, you need to be careful with PROGMEM, that is with AVR being a
Harvard machine you can burn up SRAM quickly by not using PROGMEM for
constants. For example with the LDL library you need to be sure
that LDL_ENA

Yes. To be honnest, if I comment out LDL_MAC_otaa(&mac), it runs.

Does the code run if you comment out 'lora_send("coucou", 7);
Does it still crash with simple main() { _delay_ms(1000);
stty_print("hello");}
That is start removing code until it works, when you find the line in main
that causes a crash, go into that function and start removing code until it
works

I recommend using crosstool-ng for this.

It still does - not just on AVR - also on ARM and others.
It was quite amusing when

This is likely a branch through zero.
Common causes on AVR are bad function pointers, and stack damage.

I don't understand. I have tried to comment out some lines. Sometimes
firmware runs as expected, sometimes, it continuously reboots.
When I comment out some lines or add some debug trace, firmware desn't
Can you comment out lines and have firmware run?
Could it be that your power supply is dropping and browning out?

Hello,
I'm writing a firmware for a board that uses a ATMega 1284. Firmware
continuously restarts and I'm not able to fix this bug. It looks like a
memory corruption, but after several days without finding this bug, I
doubt. Hardware seems to be bug free and runs as expected.
